    Exploring the Dynamic Evolution and Drivers of the Coupled Coordination Relationship of Carbon Emission Efficiency and Economic Benefits in Construction Land Development by Peixing Zhang, Tianlu Jin, Yuqi Wang, Honglei Guo

    Published 2025-02-01
    “…The main conclusions are as follows: (1) The CCR between CEE and economic benefits of CLD in China shows the characteristic of “improvement-stability-local decline”, and it is higher in the eastern region than in the central and western regions. (2) The decoupling of carbon emission efficiency (CEE) and economic benefits of CLD between 2003 and 2023 shows diverse trends in different provinces and time scales in China. (3) China’s eastern region are consistent with σ-convergence and β-convergence, and the gap in the level of inter-regional coupling co-ordination has narrowed. …”
